Construction of joint line in Saunderton, Buckinghamshire.

L3354. This photograph was taken looking south from the top of Saunderton Tunnel in Buckinghamshire. A new track is being laid in the deep chalk cutting penetrating the Chilterns. Temporary contractor's lines are already in use, and a number of tipping wagons are positioned along the route. The course of the down line, leading northwards towards the tunnel, can be seen to the right of the photograph.
